crypto: ahash - Fix EINPROGRESS notification callback

2017-04-10T11:09:18Z

The ahash API modifies the request's callback function in order to clean up after itself in some corner cases (unaligned final and missing finup). When the request is complete ahash will restore the original callback and everything is fine. However, when the request gets an EBUSY on a full queue, an EINPROGRESS callback is made while the request is still ongoing. In this case the ahash API will incorrectly call its own callback. This patch fixes the problem by creating a temporary request object on the stack which is used to relay EINPROGRESS back to the original completion function. This patch also adds code to preserve the original flags value. Fixes: ab6bf4e5e5e4 ("crypto: hash - Fix the pointer voodoo in...")

crypto: Replaced gcc specific attributes with macros from compiler.h

2017-01-12T16:24:39Z

Continuing from this commit: 52f5684c8e1e ("kernel: use macros from compiler.h instead of __attribute__((...))") I submitted 4 total patches. They are part of task I've taken up to increase compiler portability in the kernel. I've cleaned up the subsystems under /kernel /mm /block and /security, this patch targets /crypto. There is which provides macros for various gcc specific constructs. Eg: __weak for __attribute__((weak)). I've cleaned all instances of gcc specific attributes with the right macros for the crypto subsystem. I had to make one additional change into compiler-gcc.h for the case when one wants to use this: __attribute__((aligned) and not specify an alignment factor. From the gcc docs, this will result in the largest alignment for that data type on the target machine so I've named the macro __aligned_largest. Please advise if another name is more appropriate.

crypto: ahash - Add padding in crypto_ahash_extsize

2016-07-01T15:45:03Z

The function crypto_ahash_extsize did not include padding when computing the tfm context size. This patch fixes this by using the generic crypto_alg_extsize helper. Signed-off-by: Herbert Xu

crypto: hash - Fix page length clamping in hash walk

2016-05-05T06:27:04Z

The crypto hash walk code is broken when supplied with an offset greater than or equal to PAGE_SIZE. This patch fixes it by adjusting walk->pg and walk->offset when this happens. Cc: Reported-by: Steffen Klassert Signed-off-by: Herbert Xu

crypto: hash - Remove crypto_hash interface

2016-02-06T07:33:20Z

This patch removes all traces of the crypto_hash interface, now that everyone has switched over to shash or ahash. Signed-off-by: Herbert Xu

crypto: hash - Add crypto_has_ahash helper

2016-01-25T14:42:13Z

This patch adds the helper crypto_has_ahash which should replace crypto_has_hash. Signed-off-by: Herbert Xu

crypto: hash - Add crypto_ahash_has_setkey

2016-01-18T10:16:11Z

This patch adds a way for ahash users to determine whether a key is required by a crypto_ahash transform. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu

crypto: ahash - ensure statesize is non-zero

2015-10-13T14:28:10Z

Unlike shash algorithms, ahash drivers must implement export and import as their descriptors may contain hardware state and cannot be exported as is. Unfortunately some ahash drivers did not provide them and end up causing crashes with algif_hash. This patch adds a check to prevent these drivers from registering ahash algorithms until they are fixed. Cc: stable@vger.kernel.org Signed-off-by: Russell King Signed-off-by: Herbert Xu

crypto: replace scatterwalk_sg_next with sg_next

2015-01-26T00:34:22Z

Modify crypto drivers to use the generic SG helper since both of them are equivalent and the one from crypto is redundant. See also: 468577abe37ff7b453a9ac613e0ea155349203ae reverted in b2ab4a57b018aafbba35bff088218f5cc3d2142e Signed-off-by: Cristian Stoica Signed-off-by: Herbert Xu
